2 DESCRIPTION
The nVent RAYCHEM NRG-DM thermostat is a smart electronic thermostat designed for electrical under floor heating. It is designed to control your under floor heating in order to give you the best possible comfort at the lowest possible energy consumption. The NRG-DM is equipped with an ambient sensor and a floor sensor and is thus capable of monitoring and controlling your floor heating cables in 4 different modes (Room sensing mode / Floor sensing mode / Room sensing mode with floor limiter / No sensor mode) depending on your needs.The NRG-DM will switch on and off your floor heating in order to obtain the set-temperature. When the NRG-DM is switching on the electrical floor heating, the symbol ( ) is visible on the display.The NRG-DM is controlling your electrical floor heating in 3 working modes (see Table 1).
Working mode Description Symbol
Constant Mode In the Constant Mode, the NRG-DM is aiming for 1 temperature only. You can easily adapt this set temperature by using the +/- button
Event Mode In the Event Mode, the thermostat is working according to a weekly schedule. The Event Mode is created in order to maximize the comfort while minimizing the energy consumption of your electrical floor heating system
Boost Mode The Boost Mode is a temporary override of the Constant Mode or the Event Mode. When activating the Boost Mode, you can choose a temporary Set temperature and a duration for the Boost Mode. After this duration, the NRG-DM will automatically switch back to the last used Mode (Constant or Event)

7.2.4 ENERGY MONITORINGYou can display some statistics of the use of the NRG-DM. In order to be able to do this, the currency, the load and the cost of energy need to be filled in. In the energy monitoring menu, you will find:• Currency (what currency do you use)• Load (how much electrical heating cable is installed in
this room in kW)• Cost/unit (cost of 1 kWh)In the energy monitoring menu, you will see the values calculated for the last 2 days, for the last month & for the last year.
7.3 ENGINEER SETTINGS7.3.1 TEMPERATURE CALIBRATIONWhen running in Floor sensor mode (see 7.3.3 Sensor setting)You can calibrate the floor sensor to the actual floor temperature by using the calibration menu. The floor temperature can differ from temperature measured by the floor sensor depending on the floor construction.When running in Room sensor mode (see 7.3.3 Sensor setting)You can calibrate the ambient sensor to the actual room temperature by using the calibration menu.The NRG-DM is performing an auto calibration of the Room Sensor after each factory reset (or after first installation). The manual calibration of the Room sensor should only be
nVent.com | 15
performed after this automatic calibration and only in the few cases where the automatic calibration seems not to be 100% accurate.
7.3.2 ADAPTIVE FUNCTIONThanks to the adaptive function, the NRG-DM will know when to switch your heating on, in order to obtain the desired temperature at the desired time. The Adaptive function is only active in the Event Mode and is activated from factory. You can de-activate the Adaptive function in the Adaptive function menu.The Adaptive function wil l optimize the energy consumption to the desired comfort of the user.
7.3.3 SENSOR SETTINGThe NRG-DM can operate in different sensor settings. Some of the settings are activated in the thermostat when a physical floor sensor is installed; others are activated when there is no external sensor installed.• When there is a floor sensor installed and connected • Floor The NRG-DM is regulating the temperature based on
the input given by the floor sensor (embedded in the floor)
• Room/limit The NRG-DM is regulating the temperature based
on the input of the room sensor (integrated in the thermostat) but is making sure the floor is not exceeding a desired temperature measured by the floor sensor
• When there is no external sensor installed or connected • Room The NRG-DM is regulating the temperature based
on the input of the room sensor (integrated in the thermostat)
• No sensor The thermostat works like a regulator. It will work in
duty cycles and it will activate the electrical heating cables during a percentage of this duty cycle.
16 | nVent.com
7.3.4 TEMPERATURE SCALEThe Temperature scale settings provide the possibility to limit the minimum and maximum settable temperature in the working modes (Event Mode, Constant Mode or Boost Mode).
7.3.5 BACKLIGHTYou can define how the backlight (blue light) of the NRG-DM is reacting.There are 3 possible settings:• Auto The backlight is deactivated after 30 seconds of
inactivity• On heat The backlight lights up every time the thermostat is
heating• Constant On The back light does not go off
7.3.6 SENSORIn the Sensor setting, you select the type of sensor that is installed. The possible sensors are:• Factory = sensor delivered with the NRG-DM =
12kΩ sensor• NRG-Temp = sensor of the NRG-Temp or Green Leaf
thermostat = 10kΩ sensor• 2 kΩ sensor• 10 kΩ sensor• 12 kΩ sensor• 15 kΩ sensor• 33 kΩ sensorWith the exception of the Factory sensor and the NRG-Temp sensor, you will be asked to give reference points of your sensor at 15, 20, 25 & 30°C. If you do not have these reference points of the sensor, the NRG-DM is proposing you a standard calibration of the sensor. This might not be 100% accurate but will be close to the real values.

7.3.7 LANGUAGEThe NRG-DM is translated in to 11 languages. In this menu you can choose to use the following languages for the firmware: Czech, Dutch, English, Finnish, French, German, Lithuanian, Norwegian, Polish, Russian or Swedish.
7.3.8 FACTORY RESETIf you need to reset all the settings to the factory settings, you can use the factory reset.
7.3.9 INFORMATIONIn the information section of the thermostat, you will find information on how to contact us, on the measured temperatures and calibration and on the software version in the thermostat.
8 TROUBLE SHOOTING
In the event of damage or malfunction of one of the temperature sensors, the heating output cuts off (fail safe) and an error code is displayed.
Number Error type
E0 Room failure. NRG-DM is defective. Please replace the thermostat.
E1 Room sensor defective or short circuited. Please replace the thermostat.
E2 Floor sensor defective or short circuited. Please check or replace the external sensor *
E5 Internal overheating. Please inspect the installation
Table 3* The floor sensor may be replaced by a new one (product
reference = 1244-002952). In case of replacement of the floor sensor by a new sensor (1244-002952), the sensor selection needs to be performed and you need to choose the NRG-Temp sensor in the list of sensors (see 7.3.6 Sensor).
